GEORGE A. MANNING, OF ELKHART, INDIANA, ASSIGNOR TO C. G. CONN, 0F ELKHART, INDIANA.

DRUM.

To all whom it may concern:

Be it known that I, Gnoncn A. MANNING, a citizen of the United States, residing at Elkhart, in the county of Elkhart and State of Indiana, have invented certain new and useful Improvements in Drums, of which the following is a specification.

This invention relates to improvements in percussive musical instruments of the drum type, and has for its object to provide means for eliminating the socalled ringing sound that develops when the drum is beaten, and which, so far as I am aware, is an effect resulting from subsidiary or derivative vibrations in one or both of the drum heads. To these ends, the invention consists in associating with the drum head, preferably with the batter head and on the inner surface thereof, a damping band of freely flexible material of relatively soft structure and, therefore, having little or no percussive effect stretched or distended in a manner to hold it in contact with the membrane which forms the head. In carrying out the invention, a ribbon of silk or other fabric is found to answer well the purpose, and this is applied by stretching it independently of the head, in diametric position over the edges of the drum shell or cylinder, so that when the drum head is applied and pressed down under tension of the usual stretching means it will lie closely upon the ribbon, and in damped relation thereto, so that an effective anti-ringing device will be de veloped.

The invention will be fully understood upon reference to the accompanying drawings, in which Figure 1 is a plan view of a drum of known construction, to which the present invention is applied, as indicated by paral lel dotted lines on opposite sides of one of its diameters.

Fig. 2 is a detail sectional view on an enlarged scale.

Fig. 3 is a diametric section of the drum shown in Fig. 1, in a plane at right angles to the length of the anti-ringing ribbon.

Fig. 4: is a fragmentary side elevation Specification of Letters Patent.

partly in section, showing the method of attaching the ends of the band to the shell of the drum.

1 represents the cylinder or shell of the drum, 2 the batter head, 3 the snare head, and 4, 5, the tightening rings for said heads. 6 represents the tension rods which engage the rings and draw them toward each other in tightening the heads.

11 snare drums as generally constructed, a ringing effect derived from the snare is quite noticeable in addition to the desired quality of the tones lent by the snare, and it is the purpose of the present invention to eliminate this effect. In accomplishing this purpose, according to the particular embodiment of the invention selected for purposes of illustration, a damping strip, band, or ribbon 7 of non-percussive material is stretched diametrically across the underside of and in contact with the batter head, preferably in the same diametric relation as and through means of the snare attachments 9 beneath the snare head. The ribbon 7 is of woven fabric, and it is secured in place by means of tacks or the like 7, as shown in Figs. 2 and 4, introduced through its ends that are folded over the edges of the shell 1 in position to present the ribbon in contact with the underside of the head when the latter is pressed into position.

It is to be understood that the invention is not limited to the particular location of the anti-ringing attachment shown, for it might be associated with the snare head and on either side thereof. Nor is the invention limited to a band of the particular width shown, or to a fabric as distinguished from other material. I have found by experiment that rubber and other materials sufficiently soft to avoid percussive effect from any residual vibration will serve well the purposes of the invention.

I claim in a manner that when the head-tightening ring of the instrument is placed in position,
